The initial rise of fitness that occurs with increasing temperature is attributed to Arrhenius
kinetics, in which rates of reaction increase exponentially with increasing temperature …

Temperature has profound effects on ectotherms such as plants, invertebrates, and lower
vertebrates (Hochachka and Somero 1984; Cossins and Bowler 1987). The impact of …

By influencing physiological reaction rates'-', body temperature has a significant impact on
an ectotherm's performance (eg its ability to run, feed and interact sociallyI and ultimately on …

In many organisms, individuals in colder environments grow more slowly but are larger as
adults. This widespread pattern is embodied by two well-established rules: Bergmann's rule …

Across a range of taxa, individuals within a species differ in suites of correlated traits. These
trait complexes, known as syndromes, can have dramatic evolutionary consequences as …

In ectotherms, lower temperatures in high-latitude environments would theoretically reduce
the annual growth rates of individuals. If slower growth and resultant smaller body size …

A mechanistic understanding of the response of metabolic rate to temperature is essential
for understanding thermal ecology and metabolic adaptation. Although the Arrhenius …

The majority of ectotherms grow slower but mature at a larger body size in colder
environments. This phenomenon has puzzled biologists because classic theories of life …

Body temperature influences the performance and fitness of ectotherms. How thermal
sensitivity responds to selection for resistance to high temperature is broadly relevant in …

Body temperature (T b) profoundly affects the fitness of ectotherms. Many ectotherms use
behavior to control T b within narrow levels. These temperatures are assumed to be optimal …
